  SAP Error Message:
  WRF_APC239 Invalid purchasing list number &1: it contains only numbers
  
  Cause:
  This error occurs because the purchasing list number entered contains only numeric characters, which is not allowed in this context. SAP expects the purchasing list number to contain at least one alphabetic character or follow a specific format that includes letters. The system uses alphanumeric purchasing list numbers to differentiate and validate them properly.
  
  Explanation:
  
  Purchasing list numbers are identifiers used in SAP to group or reference purchasing documents or lists.
  The system validation checks the format of the purchasing list number.
  If the number consists only of digits, the system flags it as invalid because it expects a combination of letters and numbers or a specific pattern.
  This is often a business rule or a configuration setting in the SAP system to avoid confusion with purely numeric document numbers or IDs.
  
  
  Solution:
  
  Modify the purchasing list number to include alphabetic characters. For example, instead of 123456, use PL123456 or A123456.
  Check the naming conventions or format requirements for purchasing list numbers in your SAP system or company policy.
  If the purchasing list number is generated automatically, review the number range or generation logic to ensure it produces valid alphanumeric values.
  If this error occurs during data migration or manual entry, validate the data before input.
  Consult with your SAP MM (Materials Management) or purchasing module consultant to confirm the correct format and adjust the process accordingly.
